Cummins Announces Production Of PowerCommand® 3300 Controller For Oil And Gas Drilling Applications

Automated Engine Load Management
Offers Greater Efficiency

HOUSTON (May 4, 2015) –
Cummins Inc. (NYSE: CMI) announced
today the production of the PowerCommand (PCC) 3300 Controller for drilling
operations, offering greater drilling power module (DPM) efficiency. The
PCC 3300 monitors, meters and serves as a control system for Cummins Drilling
Power Modules, designed to maximize both engine efficiency and rig uptime
through automated engine load management and enhanced system integration. Built
and tested to perform in the harshest oil and gas drilling applications,
Cummins PCC 3300 is the perfect tool for enabling smarter, more efficient rig
operation and control under a single, integrated system.

Cummins
PCC 3300 communicates with Cummins DPMs and Kato® or AVK®
alternators to form a truly integrated drilling power system. The system maximizes
efficiency by allowing each engine and alternator to continuously communicate
with each other, providing faster response time and greater load acceptance. The
controller then uses that communication to automatically manage and distribute
engine loads, activating and deactivating drilling power modules, automatically
synchronizing and paralleling them and putting them on the bus as needed. Those
real-time adjustments enable each drilling power module to deliver more power,
faster.

Not
only is efficiency optimized by the Cummins PCC 3300, but rig productivity is
improved through smarter drilling power module control. Cummins PCC 3300 allows
the operator to preset load profiles, which automatically adjust loads between
engines, bringing additional drilling power modules online as loads increase. Shutdown
points can also be programmed, allowing drilling power modules to be taken
offline as loads decrease. By optimizing the operation and shutdown of multiple
modules automatically through load profiles, system response times are
dramatically reduced. Cummins PCC 3300 also reduces the total cost of ownership
by only running drilling power modules as needed, reducing idle run time and
the associated fuel, oil and maintenance costs that come with it.

Cummins PCC 3300 controller
is an option on drilling power module packages designed and manufactured by the
Cummins Oil and Gas Center of Excellence (COE) in Houston. All complete drilling
packages from the COE are designed and validated to Cummins extensive design
standards, and backed by a common, global warranty.

“The Cummins
PowerCommand 3300 allows
the rig to have smarter control of drilling power modules on site,” said
Patricio Escobar, Drilling Segment Leader. “The current
capabilities of Cummins PCC 3300 greatly improve engine and rig efficiency in
the short term, but its innovative design makes the system capable of even
greater integration with customer operations in the future.”
